# Supabase Tutorial 
[Supabase](https://supabase.com/) is an open source Firebase alternative.
Start your project with a Postgres database, Authentication, instant APIs, Edge Functions, Realtime subscriptions, Storage, and Vector embeddings.

## Use Supabase to log requests and see total spend across all LLM Providers (OpenAI, Azure, Anthropic, Cohere, Replicate, PaLM)
liteLLM provides `success_callbacks` and `failure_callbacks`, making it easy for you to send data to a particular provider depending on the status of your responses. 

In this case, we want to log requests to Supabase in both scenarios - when it succeeds and fails. 

### Create a supabase table 

Go to your Supabase project > go to the [Supabase SQL Editor](https://supabase.com/dashboard/projects) and create a new table with this configuration.

Note: You can change the table name. Just don't change the column names. 

```sql
create table
  public.request_logs (
    id bigint generated by default as identity,
    created_at timestamp with time zone null default now(),
    model text null default ''::text,
    messages json null default '{}'::json,
    response json null default '{}'::json,
    end_user text null default ''::text,
    status text null default ''::text,
    error json null default '{}'::json,
    response_time real null default '0'::real,
    total_cost real null,
    additional_details json null default '{}'::json,
    litellm_call_id text unique,
    primary key (id)
  ) tablespace pg_default;
```

### Use Callbacks 
Use just 2 lines of code, to instantly see costs and log your responses **across all providers** with Supabase: 

```python
litellm.success_callback=["supabase"]
litellm.failure_callback=["supabase"]
```

Complete code
```python
from litellm import completion

## set env variables
### SUPABASE
os.environ["SUPABASE_URL"] = "your-supabase-url" 
os.environ["SUPABASE_KEY"] = "your-supabase-key" 

## LLM API KEY
os.environ["OPENAI_API_KEY"] = ""

# set callbacks
litellm.success_callback=["supabase"]
litellm.failure_callback=["supabase"]

# openai call
response = completion(
  model="gpt-3.5-turbo", 
  messages=[{"role": "user", "content": "Hi 👋 - i'm openai"}],
  user="ishaan22" # identify users
) 

# bad call, expect this call to fail and get logged
response = completion(
  model="chatgpt-test", 
  messages=[{"role": "user", "content": "Hi 👋 - i'm a bad call to test error logging"}]
)
 
```

### Additional Controls 

**Identify end-user**

Pass `user` to `litellm.completion` to map your llm call to an end-user 

```python
response = completion(
  model="gpt-3.5-turbo", 
  messages=[{"role": "user", "content": "Hi 👋 - i'm openai"}],
  user="ishaan22" # identify users
) 
```

**Different Table name**

If you modified your table name, here's how to pass the new name.

```python 
litellm.modify_integration("supabase",{"table_name": "litellm_logs"})
```
